Answer:
4.62 sq ft
Step-by-step explanation:
Area of rectangle = 2.5 x 1 = 2.5
To get area of triangle we must use the altitude theorem to find the height:
let 'x' = altitude (or height)
x/1.5 = 2/x
cross-multiply to get:
x² = 3
x =
Area of triangle = 1/2(2.5)()
= 1.25 which is approx 2.12
Total area = 2.5 + 2.12 = 4.62
